and useful Improvements in Hose Attachments for Street-ashers, of a speeication.

In the accompanying drawings, Figure 1 is which the following is a vertical section of my improved hose attachment, showing one forni of constructing the swivel-joint. Figs. 2 and 3 are each vertical sections. showing modified forms of constructing Said swivel-joint.

These improvements consist of a pipe, to be attached to the street-Washer, a neck provided with a ange, a spring, and a nut, to comprise a swivei-joint for attaching hose to streetwashers, snbstant-iall y constructed and operating as hereinafter described and claimed.

In the Several figures, A isa short pipe, to be attached to the street-Washer, the object of which is to elevate the swivel-joint a snt'licient distance above the bowl ot' the casing of the street-Washer at the surface of the ground in which it is set to give freedom to play. The upper end of pipe A in Figs. l, 2, and 3 has an enlargement for providing a chamber, which is closed by a hollow screwthreaded nut, B.

C is an elbow or curved neck, having astem which ts down in the pipe A, the lower end resting on a shoulder, so that the bore of the pipe and neck are alike, so as to make a continuons smooth passagemipr the Water. The

said neck is provided with a flange, c, which Varies a little in form in the different modifi1 cations shown. In Figs. l and 2 said flange rests on a spiral spring, s, contained in the chamber, and which bears on a shoulder foi-nr ing the bottom of said chamber. Over said flange c in Fig. l the ring B rests, holding a packing-ring, b. In Fig. 2 the top surface of said flange is made spherical, and the ring B, which rests on it, is made hollow to conform tothe surface. This makes a groundjoint. In Fig. 3 the lower side of the flange@ is made spherical, and rests in a spherical seat in the bottom of the chamber, While above it and between it and the ring B is placed a spiral spring. The upper end of the curved necks in Figs. 1, 2, and 3 are provided with a screwthread for attaching the hose.

From the foregoing it'will be seen that the neck C will turn as the hose may be drawn in movi-ng around a eld, so that the hose will not be bent or crooked 'at or near the connection.

Having described my invention, I claim- The combination of the pipe A with the neck C, provided with the ange c, the spring s, and the nut B, whereby a swivel-joint is formed, substantially as described.
